Description

Technical Field

[0001] This application relates to the field of pipeline vibration reduction technology, and in particular to a pipeline vibration reduction device. Background Technology

[0002] Pipeline transportation is a fluid transport method widely used in industries such as chemical, petroleum refining, and coal chemical processing. However, due to the inconsistent frequencies of the forces exerted on pipelines by different fluids, vibration frequently occurs during pipeline transportation. Long-term pipeline vibration can cause fatigue damage to the pipeline, and may even lead to loosening or rupture at the connection between the pipeline and equipment, resulting in safety accidents and economic losses.

[0003] In related technologies, multiple load-bearing blocks are usually connected to the outer wall of the pipe. The weight of the load-bearing blocks is used to apply a load to the pipe, thereby inhibiting radial movement of the pipe.

[0004] However, the radial and axial vibrations of the pipeline occur simultaneously, and because the force frequencies of different fluids are inconsistent, the pipeline vibration will generate different dynamic loads. The load-bearing block can only apply a single load to the pipeline, resulting in poor vibration reduction effect. Utility Model Content

[0026] In related technologies, multiple load-bearing blocks are usually connected to the outer wall of the pipe. The weight of the load-bearing blocks is used to apply a load to the pipe, thereby inhibiting radial movement of the pipe.

[0027] However, the radial and axial vibrations of the pipeline occur simultaneously, and because the force frequencies of different fluids are inconsistent, the pipeline vibration will generate different dynamic loads. The load-bearing block can only apply a single load to the pipeline, resulting in poor vibration reduction effect.

[0028] To address the aforementioned technical problems, this application provides a pipeline vibration damping device, comprising: a limiting member, a vibration damping assembly, and a support assembly. The limiting member covers the outer periphery of the pipeline; the support assembly includes a first support member and a second support member, the second support member being disposed on the first support member and used to support the pipeline, the second support member and the limiting member jointly clamping the pipeline; the vibration damping assembly includes multiple connecting members, the limiting member and the first support member being connected via the connecting members, the connecting members driving the limiting member to move towards or away from the first support member, so that the limiting member conforms to the pipeline.

[0029] The pipeline vibration reduction device provided in this application covers the outer perimeter of the pipeline with a limiting member, which together with the second support member clamps the pipeline. The limiting member is connected to the support assembly using a connector. When the pipeline vibrates, the connector applies a force to the limiting member, allowing the limiting member to move toward or away from the first support member, so as to fit and tighten the pipeline, suppress pipeline vibration, and thus achieve the optimal vibration reduction effect.

[0030] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0031] Combination Figure 1 and Figure 2 As shown, this application provides a pipeline vibration damping device, including: a limiting member 100, a vibration damping component 200, and a support component 400;

[0032] The limiting element 100 covers the outer periphery of the pipe 300;

[0033] The support assembly 400 includes a first support member 410 and a second support member 420. The second support member 420 is disposed on the first support member 410 and is used to support the pipe 300. The second support member 420 and the limiting member 100 together clamp the pipe 300.

[0034] The vibration damping assembly 200 includes multiple connectors 210, a limiting member 100 and a first support member 410 connected by the connectors 210. The connectors 210 drive the limiting member 100 to move toward or away from the first support member 410 so that the limiting member 100 fits against the pipe 300.

[0035] Understandably, in combination Figure 1 and Figure 2 As shown, the limiting member 100 covers the upper part of the pipe 300, and the second support member 420 supports the lower part of the pipe 300. The limiting member 100 and the second support member 420 together clamp the pipe 300. Furthermore, both ends of the connecting member 210 are connected to the limiting member 100 and the first support member 410 respectively, so that the limiting member 100 and the connecting member 210 also jointly clamp the pipe 300. The connecting member 210 can move, thereby driving the limiting member 100 to move towards or away from the first support member 410. Even if the pipe 300 vibrates and generates dynamic loads, the clamping force applied by the limiting member 100 to the pipe 300 can be adjusted by adjusting the moving distance of the connecting member 210, so that the pipe 300 can always be tightly clamped, thereby improving the vibration reduction effect.

[0036] Specifically, the pipe vibration damping device provided in this application covers the outer peripheral wall of the pipe 300 with a limiting member 100, which together with the second support member 420 clamps the pipe 300. The limiting member 100 is connected to the support assembly 400 using a connector 210. When the pipe 300 vibrates, the connector 210 applies a force to the limiting member 100, allowing the limiting member 100 to move toward or away from the first support member 410, so as to fit and tighten the pipe 300, suppress the vibration of the pipe 300, and thus achieve the optimal vibration damping effect.

[0037] In some embodiments, combined with Figure 1 and Figure 2 As shown, the vibration damping assembly 200 also includes a rotating member 220, which is disposed on the first support member 410 and connected to the connecting member 210. The rotating member 220 rotates relative to the connecting member 210 so that the connecting member 210 moves toward or away from the first support member 410 along the drive limiting member 100.

[0038] Specifically, in combination Figure 1 and Figure 2As shown, one end of the connector 210 can be rotatably connected to the rotating member 220. When the pipe 300 vibrates under different loads, the rotating member 220 can be adjusted to rotate relative to the connector 210, thereby driving the connector 210 to move towards or away from the first support member 410. This allows the limiting member 100 connected to the connector 210 to fit tightly against the outer periphery of the pipe 300, thus suppressing the vibration of the pipe 300. The rotating member 220 can be located on the first support member 410. When the pipe 300 vibrates, the first support member 410 can provide a reverse traction force to pull the limiting member 100, further enhancing the vibration reduction effect.

[0039] Furthermore, such as Figure 1 As shown, the vibration damping assembly also includes an elastic element 230, which is sleeved on the outside of the connector 210. The elastic element 230 is configured to compress or extend when the rotating member 220 rotates relative to the connector 210.

[0040] For details, see Figure 1 As shown, the elastic element 230 is sleeved on the outside of the connector 210 and located between the connector 210 and the rotating element 220. The elastic element 230 can cooperate with the connector 210 and the rotating element 220. When the pipeline 300 vibrates and generates a dynamic load, the rotating element 220 rotates relative to the connector 210, and the elastic element 230 can be compressed or stretched to generate elastic force, so as to pull the limiting element 100 to resist the vibration of the pipeline 300 within a certain range.

[0041] In some embodiments, the connector 210 is a bolt, the elastic element 230 is a plurality of disc springs arranged sequentially along the extension direction of the bolt, and the rotating element 220 is a nut screwed to the end of the bolt.

[0042] Specifically, rotating the nut causes the bolt to move vertically, thereby fixing the limiting member 100 to clamp the pipe 300, and the disc spring provides elasticity to suppress the vibration of the pipe 300. Of course, in some other embodiments, the connecting member 210 can also be an adjusting screw, as long as it can move flexibly along its extension direction to achieve the effect of suppressing the vibration of the pipe 300, and the elastic member 230 can also be a telescopic spring or other structure, as long as different elastic moduli are applied according to different vibration loads of the pipe 300 to further suppress the vibration of the pipe 300.

[0043] In some embodiments, see [reference] Figure 2 As shown, multiple connectors 210 are respectively disposed on both sides of the pipe 300, with multiple connectors 210 on the same side spaced apart. Each connector 210 is fitted with a tensioning tube 240, which is connected to the limiting member 100.

[0044] Specifically, such as Figure 2As shown, multiple connectors 210 are provided on both sides of the pipe 300. The connectors 210 on the same side are spaced apart along the extension direction of the pipe 300 to enhance the clamping force of the limiting member 100 on the pipe 300, preventing the limiting member 100 from being lifted due to excessive vibration of the pipe 300, and further enhancing the vibration reduction effect of the pipe vibration damping device. Furthermore, the connectors 210 can be at least partially disposed within the tensioning tube 240, which is connected to the limiting member 100, so that the connectors 210 can move vertically by different distances according to different loads generated by the vibration of the pipe 300, ensuring that the limiting member 100 always tightly clamps the pipe 300, achieving a better vibration reduction effect.

[0045] Of course, in other embodiments, the top dimension of the connector 210 is larger than the inner diameter of the tension tube 240 to prevent the connector 210 from separating from the tension tube 240 and affecting the shock absorption effect.

[0046] In some embodiments, see [reference] Figure 1 As shown, it also includes a washer 500 and a vibration damping pad 600. The washer 500 is disposed on the contact side between the elastic member 230 and the connector 210, and the vibration damping pad 600 is disposed on the contact side between the pipe 300 and the limiting member 100.

[0047] It is understandable that, such as Figure 1 As shown, a washer 500 can be added to the end where the elastic element 230 contacts the connector 210 to reduce the force generated by the vibration of the pipe 300 from being transmitted to the connector 210 or the elastic element 230, thereby enhancing the vibration reduction effect. Furthermore, a vibration damping pad 600 can be provided on the side of the limiting element 100 that contacts the pipe 300. The vibration damping pad 600 is made of a flexible material to mitigate the impact of the pipe 300 vibration on the limiting element 100 and the connector 210, preventing damage to the limiting element 100 or the connector 210 and further enhancing the vibration reduction effect of the pipe vibration damping device.

[0048] In some implementation methods, combined with Figure 1 and Figure 2 As shown, the first support member 410 includes a first base plate 411, a second base plate 412 and a plurality of reinforcing ribs 413. The first base plate 411 and the second base plate 412 are spaced apart, and the reinforcing ribs 413 are disposed between the first base plate 411 and the second base plate 412. The first base plate 411 has a plurality of through holes, and the connector 210 passes through the through holes to connect with the rotating member 220.

[0049] Specifically, in combination Figure 1 and Figure 2As shown, the first base plate 411 and the second base plate 412 are both located below the pipe 300 and are arranged in parallel and spaced apart to form a base to support the pipe 300. Furthermore, multiple reinforcing ribs 413 can be added between the first base plate 411 and the second base plate 412. The upper and lower ends of the reinforcing ribs 413 are respectively connected to the first base plate 411 and the second base plate 412. At the same time, the reinforcing ribs 413 are evenly arranged along the spacing direction perpendicular to the first base plate 411 and the second base plate 412 to form an I-shaped steel structure with a cross-section, thereby strengthening the support force and preventing the first support member 410 from deforming.

[0050] And, as Figure 1 and Figure 2 As shown, a plurality of through holes are provided on the first base plate 411 located near the pipe 300. The bottom end of the connector 210 passes through the through holes and is rotatably connected to the rotating member 220 to provide resistance. When the rotating member 220 rotates relative to the connector 210, the connector 210 can apply force to the limiting member 100, thereby fitting and tightening the pipe 300 and suppressing the vibration of the pipe 300.

[0051] Furthermore, in combination Figure 1 and Figure 2 As shown, the second support member 420 is disposed on the first base plate 411. The second support member 420 includes a pipe support 421. A support groove is formed on the surface of the pipe support 421. The curvature of the support groove is adapted to the curvature of the outer wall of the pipe 300.

[0052] Specifically, such as Figure 1 and Figure 2 As shown, the pipe support 421 has a support groove formed on its surface facing the pipe 300. The curvature of the support groove matches the curvature of the outer wall of the pipe 300 so that the pipe support 421 can cover the pipe 300 and, together with the limiting member 100 covering the upper half of the pipe 300, clamp the pipe 300. Of course, the main function of the pipe support 421 is to support the pipe 300 and prevent the pipe 300 from directly contacting the ground, which would cause damage to the pipe 300.

[0053] Furthermore, such as Figure 1 and Figure 2 As shown, the second support member 420 also includes a support column 422, which is disposed on the first support member 410 and connected to the bottom surface of the pipe support 421. It can be understood that the pipe support 421 is connected to the first support member 410 or the first base plate 411 via the support column 422 to support the pipe 300 and prevent deformation of the pipe support 421. The support column 422 can be a reinforcing rib or a connecting block structure, as long as it can support the pipe 300 and prevent deformation of the pipe support 421.

[0054] In some embodiments, such as Figure 1As shown, it also includes a friction pad 700, which is disposed on the contact side between the second support member 420 and the first support member 410. It is understood that different fluids with high temperatures often pass through the inside of the pipe 300, causing the pipe 300 to expand or vibrate. Therefore, a friction pad 700 can be disposed at the contact end between the second support member 420 (i.e., support column 422) and the first support member 410. The friction pad 700 reduces the frictional force acting on the second support member 420 when the pipe 300 expands and vibrates, thus preventing misalignment or deviation between the second support member 420 and the first support member 410.

This application is intended to cover any variations, uses, or adaptations of this application that follow the general principles of this application and include common knowledge or customary techniques in the art not disclosed herein.
